Serial No. 614,289.

' To all whom 'it may concern.

.Be it known that I, \VILLIAM R. BUnnows, a; citizen of the United'States, and a resident of Newark, in the county of Essex and state'of New Jersey, have invented certain new and useful Improvement's'in Machines for the Manufacture of Vacuum-Receptacles, of which the following is a specification. I The invention relates to a novel machine for the manufacture of vacuum receptacles of the character comprising an inner receptacle or bot-tle member and an outer re- 4 ceptacle or bottle member separated by a space. from each other and out of contact with eachother except at their lip edges where they are fused together, a vacuum being formed in the chambenbetween the f two members. It has been customary in the formation of vacuum receptacles, especially when they are of considerable size, to interpose supporting studs or the like between the lower portions of the members thereof for aiding in enabling the inner or receiving member to resist strains.

, My invention pertains more particularly to a novel machine by which the inner and outer receptacle or bottle members may be properly, effectually and with reasonable rapidity seamed together at their lip edges,

and the interior of the neck of the inner bottle member formed to receive a stopper. My "invention is, therefore, confined to the treatment of the upper ends of the bottle members for their format-ion,"the formation of the lower end of the outer bottle member being left for accomplishment by any suitable means or by a machine-which I have specially invented for that purpose and which is shown in anapplication for Letters Patent for thesame filed concurrently herewith bearing Serial Number 614,288.

In its referred form themachine of my present invention comprises a rotary frame carrying a plurality of chuck mechanisms adapted to support the inner and outer bot tle or receptacle members one wit in the other, and means for rotating said 1echanisms whenthe frame is at its at rest positions adjacentto burners for directing flames against the'upperlip edges of the bottle members, said chuck mechanisms being in themselves at rest when said rotary frame is in motion. I preferably provide the rotary frame with four chuck-mechanisms so that at least three pairs of bottle and neck members may, in the at-rest periods of the rotary frame, be rotated in the presence of flames from the gas burners while the fourth clu[ck-mechanism is .at the front of the machine inv position for the removal of a finished receptacle and the reception of a pair of members to be carried on the next intermittent movement of the rotary frame to a burner. The chuck mechanisms are of special character and adapted to independently support and simultaneously rotate the bottle members with the inncrmemb'er accurately located within the outer member. The gas burners which first act upon the bottle members are for heating the glass thereof preparatory' to the action on the glass of the final burner at which the important work is performed. Preferably the upper lip edge. of the inner bottle member will. initially project slightly above the lip edge of the outer bottle member, and during the rotation of said membersin the presence of the flame from-the final burner, said up wardly projecting portion of the inner member will lap over upon and becom e fused to the upper edgepf the outer bottle member. At this stage of the operation I preferably introducea tool or tools of inverted truncated cone-shape into the mouth of the inner bottle member so as to effect the proper contour therein for the reception of a stopper ruch as would be required when the bottle or receptacle is placed in use.

The invention will be fully understood from the detailed description hereinafter presented, referencebein had to the accompanying drawings, in w ich:

Figure 1 is a top plan of a machine constructed in accordance with and embodying the invention; Fig. 2 is a front view, partly in section andpartly'broken away, of the same; Fig. 3 isa vertical section, on a larger scale. than Figs. 1 and 2, of oneof the rotary chucks and its cooperative mechanism for receiving and holding the inner and outer bottle-blanks preparatory to their union; Fig. 4 is a top view-0f the same; Fig. 5 is a horizontal section of the same on the dotted line 55 of Eig. 3; Fig. 6 is a detachd'top view, corresponding with F ig.

at, of one of the rotary frames or chucks but showing the bottle-blank clamping devices in their releasing or initial. condition ready to permit. 'the removal of or receive the bottlewblainks; Fig. 7 is a detached top view of the supporting frame for the inner bottle-blank; Fig. '8 is an enlarged vertical section through the upper portion of the bottle-blanks after they have for a time been subjected to rotationin the presence of a flame directed against their lip edges for softening and welding the same together; Fig. 9 is alike view showing a further stage in the formation of the upper end of the bottle, a hand tool or reamer being shown as inserted within the outer portion of the end of the inner member of the bottle, and Fig. 10 is a like View showing the finishing stage in the formation of the upper end of the bottle, a hand tool or reamer having a long tapered body portion being shown as within the inner member of the bottle for giving final form thereto.

In the drawings, designates the table or bed-plate of the machine, 16 a horizontal rotary frame supported above said bed-plate, and 17 a vertical shaft having a mounted upon its upper end said frame 16.

Tie frame 16 is shown as a spider-frame comprising four equally spaced-apart'radial arms numbered, respectively, 18, 19, 20, 21,

' its outer end with a vertical bearing sleeve I 24 containing a rotary sleeve 25 (Fig; 3). upon whose lower end are secured the gear and said frame is to be moved by hand, being given a one-quarter turn at each movement and yieldingly locked at the end of each movement by aspring latch. 22 arranged to engage a shoulder 23 on the outer end of the said arms as the latter are moved against it. Nhile each arm of the frame 16 is formed with a shoulder 23, one latch 22 is sufficient to hold the entireframe stationary during its at-rest periods.

'- Each arm of the frame 16 isformed near wheels 26, 27 and whose upper end is formed with an annular shoulder 28 and supported on ball-bearings 29 at the upper end of the sleeve 24. Each sleeve 25.has secured within it, by a screw 30, a tubular ,rod 31 containing within it a rod 32 and having secured on its upper end a disk or plate 33 carrying a series, say three, vertical equally spaced-apart rods 34 which form, with the cup 35, a frame to hold the inner bottle or bottleblank 36 properly within the outer bottle-blank 37 during the welding or fusing of the lip edges of said blanks together in the operation of completing the formation of the upper end of the bottle.

The cup is concaved to snugly receive the lower end of the inner bottle member 36 and formed or secured on the upper end of the rod 32. A spring 38 encompasses the re between the cup and disk 33 and atl'ords an adjustable seat for saidcup. The lower end of the rod 32 is threaded to receive a nut 39 by which the action of the spi is restrained and which may be used to draw the rod downwardly or in which is mounted a vertical shaft 42 release it somewhat to move upwardly in Each sleeve 24 of each arm of the frame 7 16 has clamped on it a horizontal bar 40 (Fig. 5) standing preferably at right angles 4 to the frame-arm and having secured to its outer end a vertical tubular rod 41-w1thcarrying at its lower end a pinion wheel 43 in constant mesh with the aforesaid gearwheel 27 (Fig. 3) and at its upper end a pinion wheel 44 in constant mesh with a ring gear wheel 45, which is rotatably -mounted in a horizontal open frame 46 supported from the tubular rod 41 and secured thereto by a' set screw 147. The ring gear wheel and frame 46 concentrically encircle the bottle members 36, 37 and are above the gear wheel 27. The inner bottlemember 36 is held by the cup 35and rods 34 and the outer bottle-member 37 which has an open lower'end, by a clamping mechanism secured to the ring gear wheel .45 and comprising (Figs. 4 and 6) a stationary arc-shaped bar 47, an arc-shapedbar 48 pivoted at one end, as at 49, and having a handle 50 medially pivoted thereto at the other end, a link 51 pivoted at one end to the inner end of said handle (at 52, Fig.5) and at the ot er end, at 53, at a fixed point, and a series f preferably two bracket-bars or plates 54 and one bar or plate 154 faced preferably with asbestos, the bracket bars or plat-es54 being rendered radially adjustable by means of slots in their horizontal members and set-screws 57, and the bar'or plate 154 being carried by rods 55 mounted in the vertical member of a bracket 56 which is secured to the pivoted arcshaped bar 48. Upon the rods 55 between the vertical member of the bracket 56 and the plate or bar 154 are coiled springs 58 plate or bar and gently, though firmly, press the asbestos pal carried thereby against the outer bottle-member 37. a v

In Fig. 6 I show the clamping mechanism carried by the ring gear wheel 45 in its open condition ready to receive or release the bot tle-members, while in Fig. 4 said mechanism is shown in its closed condition engaging the outer bottle-member. Then the handle 50 is turned outwardly to. the left, looking at Fig. 4, it will turn the bar48 outwardly to the position shown in Fig. 6 and thereby release the bottle-member 37, and when the movement of said handle is reversed and said handle restored to the. position shown in Fig. it will cause the clamping devices to engage said bottle-member, saidhandle then by reason of its deflected inner end carrying the pivot point 52 outwardly beyond a center line through the pivot point 53 and 15 ing the bottle-members.

the pivotal point of said handle w1th the bar 48 locking the clamping devices in their closed position.

Each arm of the frame 16 is equipped 5 with the mechanism I have just described comprising (Fig. 3) the bearing sleeve 24,

rotary sleeve 25, gear-wheels 26, 27,*rods 31,

32, disk 33, rods 34, cup-support 35, spring 38, bar 40, rods 41, 42, pinion wheels 43, 44,

ring gear wheel 45, open frame 46 and the clamping device's secured on said ring gear wheel, and said mechanism as a whole may be conveniently considered as a rotary chuck mechanism for vertically holding and rotat- There will be no rotation of the chuck mechanism and bottlemembers, however, except when the gear wheel 26 of a chuck mechanism is in engagementwith a driving gear wheel of the driving mechanism.' \Vhen the frame 16 is being moved on' its quarter-turns all the chuckmechanisms are in themselves at rest, and in the machine presented herein when the frame. 16 is at its. at-rest periods all of the '35 chuck-mechanisms will be in rotation with the exception of the one then at the front of the machine, that oneheing idle to permit theattendant to'withdraw therefrom the bottle-members then fused'together at 30 their lip edges and insert thereinbottleblanks or members 36, 37 to have theirlip edges fusedtogether duringthe'subsequentoperation of the machine. The mechanisms for driving the chuck mechan'isms, with-the exception of the front one of said mechanisms, at the at-rest periods of the frame 16 may be understood from Figs. 1 and 2, and comprise a main driving gearwheel 59 preferably located below the bed plate or table 40 15,'a series of three vertical shafts 60 extending through the bed-plate 15 and mounted in vertical bearings 61 secured upon said bed-plate, gearwheels 62 secured on the lower ends of said shafts 60 and always in mesh with said gear-wheel, 59 and gear wheels63 secured lipon the upper ends of said shafts 60, said shafts 60 and gearwheels 63 being so positioned with relation to the chuck mechanisms carried by the frame 16, that when said frame is moved to an at rest position, such as illustrated in Fig.1, the gear-wheels 26 thereof will move into engagement with the gear-wheels 63 and be rotated thereby. There are four chuekmechanisms carried by the frame 16,

but I provide only three shafts carrying gear-wheels 63, and hence when the frame 16 is moved to an at rest position, the two side and one. rear chuck-mechanisms so will be set in rotation from the gearwheels 63, while the front chuck-mechanism will remain idle, so that as hereinbefbre explained the operator may withdraw the bottle therefrom and insert, bottle members 55 thereto. The gear-wheels 63 have a con-- stant rotation, but have no influence on the chuck mechanisms carried,by the frame 16, except when said frame isat an at rest position. The gear-wheel 59 drives the gearwheels 62, shafts 60 and gear-wheels 63 and it is driven from .a pulley-wheel 64 around which a belt 65 leading from a pulley-wheel 66 on the main driving shaft 67 passes.

The rotation of the gear-wheel 26 of a chuck mechanism from "a gear-wheel 63 results in the rotation of the sleeve 25 and parts connected therewith and actuated therefrom. The rotation of the sleeve 25 results in the tubular rod 31, to which it isconnected, being rotated, and since the disk 33 and rods 34 are connected with the tubular rod 31, they likewise will be rotated. The rod 82 is clamped to the rod 31 bythe tension of the spring 38 and application of the nut 39, and hence it and the disk or plate 35 and bottle-member 36 will rotate with the rotation of the-tubular rod 31, causing the bottle-member 36 to turn on its vertical axis. The gear-wheel 27 is secured to the sleeve 25, as shown in Fig. 3, and hence when said sleeve is rotated, said gear-wheel 27 will also rotate and impart rotary movement to the pinion-wheel 43, rod 42 and pinionwheel 44, and at this time the wheel44 will impart motion to the-ring gear-wheel 45, causing the latter to rotate in time with the rotation of the rods 31, 32 and impart through the clamping mechanisms carried by it, rotary movement to the outer bottle member 37, the latter turning on its vertical axis correspondingly with the movement of the inner bottle member 36. \Vhen there fore the frame .16 is at an at rest position three of the chuck-mechanisms just hereinbefore described, such mechanism being duplicated for each arm of the frame 16, will be in motion or driven by the gear wheels 63, while the other chuck-mechanism will stand idle to permit the removal of one bottle and the insertion of two bottle blanks 119 therein for treatment. 7 i The bottle blanks or members 36, 37 will initially have the relation to each other illustrated in Fig. 3, said inner member being separated from. the outer member by a space and the upper edge of the neck or lip. of the inner member being extended slightly higher than the upper edge or lip of the outer bottle-member. The fusing or welding of the upper or lip-edges of the bot- 120 tle-members requires of course the softening and melting of said edges and the engage ment of the edge of the inner bottle-member with that of the outer bottle-member, and

to effect this softening and melting of the I glass, I provide adjacent to the right hand and rear chuck-mechanisms at their at rest positions, looking at Fig. 1, gas-burners 68, 69 for directing flames against the upper edges of the bottle-members held in the at rest periods of the frame 16 adjacent to said burners. lVhile the burners 68, 69 are directing their flames against the upper edges oi the bottle-members the chuck-mechanisms holding said members are in rotation, as herembeiore explained, and hence the flames are enabled to act against said edges in a uniform manner-and effect the heating tion by means of a set-screw 7 5.

72 also permit. vertical adjustment of the ments permitted, the operator-may manipuofthe glass thereat. "Atthe left hand side of th machine, looking at Fig. 1, I provide a Bunsen burner 70' in positionto-direct its fiame strongly against the upper edges of the bottle-members j for the purpose of softening and melting the edges thereof and causing said edges. to fuse together. The

burner 70 is held by a bracket 71 upon the upper end ofa set of toggle levers 72 which are pivoted at-their lower ends to a rod 73 held in a vertical sleeve 74, said rod-being adjustable vertically in said sleeve and being rigidly secured in" any adjusted posi- The levers burner 70, and the sleeve 74 and nut/Z5v also permit angular adjustment: ofthe rod 73,-

with the result that with the various adjustlate. or direct the flame from the 'burner'TO to secure the highest efficiency therefrom in its action on theglassf The edges of the bottle-members become heated att-he' burners 68, 69 preparatory to their final treatment at the burner 70, andone of the first etiects attained at the burner 70 is that the upwardly extending edge portion of the inner bottle member 36 will lap upon the upper edges of the outer bottle member, as shown in Fig. 8 and then that the adjoining edges of said members will melt and become fused together. WVhilc the bottle- 'members are being acted on by the flame from the burner 70, I impart 'the proper shape to the neck of the bottle, more particularly the bore of the neck of the innermember by means of tools 7 6, 7 7, as shown in Figs. 9 and 10, the tool 6. having a lower truncated cone section with rather iabrupt 1 surfaces and being used to tapem'downwardly and inwardly the upper inner edges 01'' the bottle-neck, the action being against the neck-portion. of the inner member 36. A fter the tool 76 has beenused to the extent indicated in Fig. 9, it is withdrawn and the tool 77 having a. long gently-tapered body portion is applied to the inner bottle-memher, said tapered portion of the tool being inserted within the neck of the inner memher and imparting the requisite shape and character thereto to enable said member to properly receive and retain a cork for clos ing the bottle when the latter is in use.

While one bottle is being treated at the burner to bring it to the condition illustrated in Fig. 10, the members for two other bottles are being n operlv heated at the burners 68, 69 preparatory to their treatment when they reach the burner 7 0 for converting theminto the condition shown in Fig. 1 O, in which it will be seen that'the bottle-members have been properly united and shaped to theirfinal conditiom'so'far as the-upper end of the bottle is concerned.

After each bottle has received its finishing treatment and been completed to the extent,

represented in Fig. 10, the operator will manually give the frame 16 a quarter-turn so as to carry the bottle-members which may be in the front chuck mechanism to position in line withthe burner 68, the bottle-members which were adjacent to the burner 68 to the burner 69,'the bottle members which were adjacent to the burner,v 69 to position adjacent to the burner 7 O for final treatment,

specially designed to create the lower end of the 'bottle member and which has been made the subject of a separate application for Letters Patent filed herewith bearing Serial No. 614,288. Upon the removal of the bottle completed to the extent shown in Fig. it from the front chuck mechanism, another pair of bottle-members 36, 37 will be introduced to said chuck mechanism, the

member 36 being set within the rods 34 and upon the seat 35, and the member 37,being introduced over the member and supported upon the upper ends or the rods 34:. The rods 34 confine and aid in holding and supporting the member 36, and they support the outer member 37 and at the same time said rods perform the important duty of maintaining the member concentr cally within the member 37, so that there will be a uniform space between said members. -The rods 34: are preferably in diameter nearly equal to the horizontal width of the space between the members 36, 37. in introducing the bottle members to the ma chine itwill sometimes be found that slight variations therein in the shape of their upper portions will necessitate a vertical adjustment of the member 36 with respect to the member 37, so that the proper space may be left between the uppei or shoulder portions of. said members, and thisadjustment may beattained by turning the nut 39 so as to draw the rod 32 and seat 35 downwardly or permit the same to move slightly upwardlyi When the bottle members what more are introduced to the chuck mechanism the operator will always'observe whether there a proper space present between the upper -il1 llldf portions thereof and'if this space .Ollld not be present then the inner bottle member with respect thereto. In the subjection of the upper edges of the bottle members to the final burner 70 Iso direct the heat from said burner that the edge of the inner member becomes somegreatly heated than the edge of the outer member and as soon'as the edge of. the inner member has softened sufficiently, I touch the same 'with a carbon tool, such as 76, for causing it to. lap over upon the edge of the outerbottlemember, after which theaction'of the flame serves to -it'use said edges together. v I .do not limit my invention to the details of construction hereinbefore described, since the same may be variously modified within the scope of the claims. I
